newb question, I'm aware.
My t2i has been giving me this message and (obviously) stopping shooting. I've looked it up and all I can find is that it could be due to 2 things- slow SD card and formatting the card. I have class 10 FujiFilm cards, so that should not be the problem. As far as formatting, I always format cards before using so I don't see why this is happening. HOW DO I FIX THIS.
